Title: Improvements in telephone or like systems
IPC: H04Q1/36
Filed: 1943-07-15
Abstract: 566,934. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. July 15, 1943, No. 11516. Convention date, Sept. 11, 1942. [Class 40 (iv)] In an inter-exchange system, each train of impulses is converted at an outgoing repeater into a single impulse of variable duration which is converted back to the original form at an incoming repeater. As shown, repeaters 100, 400 terminating a two-way junction 10 are accessible to first selectors 104, 404 and are individual to incoming selectors 105, 405. A simplex circuit on the junction which includes relays R255, R260, R265 in the repeater 100 and R355, R360, R365 in the repeater 400, is normally earthed at both ends, and upon seizure of the repeater 100, guard relay R130 replaces the earth connection at that end by battery, causing the operation of all the relays except R265, this relay and R365 being polarized to energize only on incoming calls. R130 also disconnects the incoming selector 105. Each impulse train is repeated by line relay R140 to a step-by-step switch 200, the arcuate wiper 201 of which bridges a number of terminals equal to the number of impulses. As soon as this switch moves off-normal, relay R290 connects up R180 to open the simplex circuit and starts a clutch-driven switch 210 which performs a single rotation and then unlocks R290. The terminals of the switches 200, 210 are interconnected to maintain R180 as long as wiper 211 encounters terminals that are marked over the arcuate wiper 201, whereupon the outgoing impulse is terminated. The switch 200 is restored on the relapse of dialling relay R120. At the repeater 400, the initial operation of polarized relay R365 energizes seizure relay R370, whereupon cut-off relay R470 closes a loop through R460 to the incoming selector 405. During the relapse of R365 in response to each digital impulse, a clutchdriven commutator 321 rotates to control R350 and a condenser 339 is alternately charged and discharged through impulse relay R345. R340 operates to shunt R460 to improve the impulsing circuit. The current reversal on the reply of the called party operates R460, which opens the upper leg of the simplex circuit, so that R355 and R255 fall back and the latter connects up reversing relay R150 to repeat the reply signal. When the calling party hangs up, the relapse of R140 causes the transmission of an impulse corresponding to the digit 1 which is without effect on the selector train at the distant exchange, and the subsequent relapse of guard relay R130 reconnects earth to the simplex circuit, whereupon the continued release of R365 causes the relapse of seizure relay R370, which is retarded by a dashpot. R470 in falling back opens the loop to the incoming selector 405 and shunts down the line relay of the connector. Specification 555,097 is referred to.

Abstract: 275,311. Thompson, T. May 3, 1926. Addition to 235,308. Cooking-stoves; boilers, arrangement of.-The range according to the parent Specification is modified by arranging the firebox a and boiler b transversely of, and making them of substantially the same width as, the range. The passage of hot gases from the firebox a to the uptake e is controlled by a damper d, which may be set to cause them to traverse either the front and rear boiler flues c, c<1> or flues i around the sides, bottom and back of the oven j. The boiler flue c<1> is fitted with a cleaning-door c<2> which is normally held in the closed position by a catch c<4>, but which may be opened to dump ashes and soot for removal through a door c<3> in the side of the range. Fig. 4 shows a modification in which an additional chamber k, traversed by the hot gases under control of a damper d<1>, is arranged above the main boiler b and fitted with an oven or hot closet, or, as shown, with a second boiler l. The boilers b, l, which are preferably cylindrical and furnished with external gills, are either connected in series or independent so that two separate supplies of hot water are available. The second boiler l may be constructed as a calorifier, in which case the gilled outer chamber n, Fig. 5, receives water, for use in a radiator system, from the main boiler b, which water is further heabed by the fire gases and serves to heat an additional supply for domestic purposes, passing through the inner corrugated chamber o.

Filed: 1973-03-09
Abstract: 1430794 Road surfaces FRANCE MINISTER OF EQUIPMENT 9 March 1973 [17 March 1972] 11645/73 Heading B2E [Also in Division E1] A road is coated by spreading thereon a coating consisting of a polymer and mineral particles, the surface of the resulting layer being mechanically roughened. The polymer may be applied by spreading as a slurry or paste and may comprise thermoplastic polymers (e.g. polyethylene, p.v.c., polystyrene, polyacrylics, or polyamides), elastomers such as natural or synthetic rubber, or thermosetting resin (e.g. phenol-formaldehyde, polyester, polyepoxide or polyurethane). The aggregate consists of mineral particles of limestone and/ or silica (sand). The roughness of the surface layer may be caused by treatment with a roller when the polymer is in a plastic state to form spaced pyramidal frusta on the surface of the coating. Where the polymer is thermosetting it is cured in situ.

Abstract: 438,002. Electromagnetic and mercury switches. PAYNE, M., 50, Hook Road, Surbiton, Surrey. April 24, 1935, No. 12348. [Class 38 (v)] An electric switch of the type in which the switch contacts are enclosed in a sealed vessel from which air is excluded, connection between the contacts being completed by the action of a plunger whose movements are effected by an electromagnet mounted outside the vessel, have the sealed vessel and the surrounding electromagnet disposed within a closed housing and surrounded by a solid insulating filling for the purpose of protecting the switch parts against displacement and damage. As shown in the Figure, the complete switch including the electromagnet e surrounding the sealed switch vessel a is positioned within an outer tubular housing h and the space surrounding the switch within the outer housing is filled with pitch or similar waterproof insulating material thus preserving the switch vessel, which may be of glass, from injury and rendering the switch impervious to moisture. Leads from the switch and operating electromagnet pass upwardly to terminal blocks k within a terminal box i mounted on the upper end of the housing h. The switch is operated by downward attraction of the plunger l which causes the mercury m to rise above the insulating sleeve n and establish contact with the central pin o.

Patent GB-601165-A (GB)
Title: Improvements in filter elements
IPC: B01D39/18
Filed: 1945-05-17
Abstract: An edge filter consists of a stack of layers of material formed with uneven surfaces, the pores of which are closed by an impregnating substance, the contacting raised surfaces of the layers being adhered together by a cementitious medium so that the layers are formed into a single unit.  The impregnating medium may be a polymerisable phenolic resin which serves also to cement the contacting surfaces together.  As a supplementary procedure, when the impregnated layers are pressed together, but before polymerisation, the exterior of the stack may be coated by painting, spraying, or dipping, with a polymerisable cementitious material, the exterior of the stack being polished after the polymerisation.  The layers may consist of discs of crepe paper which are secured together with the surface ridges of each layer either substantially parallel or with a slight deviation from parallelism, to those of the adjacent layer.
